摘　　要：在理论分析与计算的基础上研制了一种用于140Mb/s长波光纤通信的新型高灵敏度光接收组件,组件采用混合集成电路技术制成,由InGaAs/InP SAGM雪崩光电二极管和硅双极晶体管互阻型前置放大器组成.工作波长为1.3μm时,理论计算的灵敏度为-48.6dBm,实际测量值为-47dBm,优于现有的PIN/FET光接收组件或Ge雪崩光电二极管.Based on theoretical analysis and computation, a new type of high sensitivity optical receiver module for 140Mb/s long-wavelength optical fiber communication is devel-oped. The optical receiver consists of an InGaAs/InP SAGM avalanche photodiode (APD)and a silicon bipolar junction transistor (BJT) transimpedance preamplifier. It is hybrid-in-tegrated. The calculated sensitivity at 1.3μm is -48.6dBm and the measured one is -47dBm,which is superior to those obtained with available PIN/FET, or Ge APD.
